Order Entry & ProcessingQuestion 83 of 100
A prescription is written with the sig: ii tabs PO q6h PRN pain. Which set of patient directions is correct?
a.Take 2 tablets by mouth every 6 days as needed for pain
b.Take 2 tablets by mouth four times daily on a fixed schedule
c.Place 2 tablets under the tongue every 6 hours as needed for pain
d.Take 2 tablets by mouth every 6 hours as needed for pain
Explanation
ii = two, PO = by mouth, q6h = every 6 hours, PRN = as needed. Nothing in the sig makes the dose scheduled rather than as-needed, and PO is by mouth, not sublingual (SL). The most tempting distractor drops PRN and converts q6h into a fixed four-times-daily schedule.
